We call that limp mode around here.

Check your wire configuration again, make sure everything is plugged in correctly, and all the wires are in the right place.

Search the form for limp mode for more info.

Here is someone having the same problem:

Check your coil pack, the connections. Most likely, one of your coil packs isnt working. So give it a look, and report back.
